Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric processing, in particular to a trimming device used for non-woven fabric processing. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are made of polyester fibers and polyester fibers. They are made through a needle-punching process and can be made into different thicknesses, feels, hardness, etc. During the production process of non-woven fabrics, the uneven edges need to be cut, so a cutting device is required.

[0003] Among them, after searching, it was found that there is an application number CN202022759927.7, which discloses a cutting device for non-woven fabric processing, including a base, the upper end surface of the base is fixedly connected to a first side plate, and the side edge of the first side plate is provided with a slide groove, and has a base, the upper end surface of the base is fixedly connected to the first side plate, and the side edge of the first side plate is provided with a slide groove, and has a first motor, a screw, a movable plate, an electric cylinder, etc., which can adjust the left and right horizontal position of the tool through the electric cylinder, so that it is suitable for non-woven fabrics of different widths. Then the first motor drives the screw to rotate, and the screw moves the tool up and down through the thread action to trim the non-woven fabric. The edge cutting machine is easy to use and has a simple structure, which reduces labor intensity while improving production efficiency. The air pump provides power through the setting of the collection trough, air pump, ash absorption tray, etc. The ash absorption tray can suck the debris generated in the edge cutting process into the collection trough for unified treatment, which reduces garbage discharge while ensuring the normal operation of the machine. The setting of the pressure roller can stretch and flatten the non-woven fabric through the pressure roller before edge cutting, so that the non-woven fabric is in a straight state, making edge cutting more convenient. The setting of the knife groove can well protect the tool, avoid the generated debris entering the second motor to affect the operation of the tool, and avoid the tool being directly exposed to cause safety accidents.

[0004] However, after research, it was found that: during the trimming process, the device does not have a structure to collect the waste generated by trimming, and the staff is completely required to collect the trimming waste. The use effect is not good enough, and there is no structure to roll and unload the non-woven fabric after trimming. The degree of integration is not high enough, and there is no structure to limit the non-woven fabric. During the trimming process, the non-woven fabric is prone to deviate, and the trimming effect is not good enough. Therefore, a new device is provided to solve this problem. Utility Model Content
